Building the shed on supports keeps groundwater from soaking into it. Your options are limited if your shed is already sitting directly on the ground. You could use heavy machinery to lift the shed and then add a support structure under the shed. Most sheds installed by professionals are built up off of the ground.
This creates a water-repelling barrier so the water is not absorbed. If you are painting in conjunction with felting the roof, paint the roof in between cleaning the roof and applying the new felt.
Bubble wrap is a cheap and effective way to insulate a shed, but you can also use standard fiberglass insulation. Stapling insulation to the studs creates a small air pocket between the outer paneling and the insulation, which helps reduce moisture.
You’ll need to set up a ladder so you can reach the roof. You may also want to have someone on another ladder at the other end of the roof to help you. Write the numbers down so you don’t forget them.
If you have multiple options of roof felt, you’ll have to choose what is in your price range and seems like quality felt.
Be sure to dispose of the felt in the garbage once it is all removed.
Be sure to toss the nails into a bucket or trash barrel so they don’t end up in your yard. Loose nails can pop mower tires or end up in someone’s foot if you leave them on the ground.
The width of the rolls of felt you bought and the size of the roof will determine how many pieces of felt you need to lay.
You’ll need to use nails that are at about 20mm (⅘ inch) long to ensure they go through the felt and secure into the roof.
Cover the whole side of the roof in this way. You may only need one or two pieces, depending on the size of the roof and the size of the felt roll. If you only need to use one piece, move to the other side of the roof.
Since the felt on the sides of the roof form a crack at the top, it’s important to cover this with a final solid piece.
